Parashu Kharel, professor in ÈÕ±¾avÊÓƵ's College of Natural Sciences, will study advanced materials needed for quantum computing. 

Quantum computers process vast amounts of information quickly, allowing them to solve complex problems that would be nearly impossible for normal, "classical" computers to do. Scientists believe quantum technologies may be able to eventually revolutionize industries like health care, finance and materials science.

But before this revolutionary technology can be fully deployed, researchers must first advance the fundamental science behind quantum technologies. A collaborative National Science Foundation-backed project in ÈÕ±¾avÊÓƵ's  College of Natural Sciences — led by professor Parashu Kharel — expects to do just that. 

For quantum technologies to be successful, they must be able to store, control and protect quantum information, known as qubits. Magnetic materials play a key role in this process because they act like organized teams of tiny magnets that protect and control qubits. For this project, the research team — which includes faculty members from the University of Northern Iowa and the University of Virginia — must identify the metals that can best host these teams of tiny magnets.

At the center of this research are a group of compounds known as Heusler alloys — mixtures of several metals, some of which may have magnetic elements. Kharel, a faculty member in the Department of Chemistry, Biochemistry and Physics, has been studying Heusler alloys for a number of years. Previous research has found that Heusler alloys have special properties that can host the complex magnetic arrangements needed for quantum computing. The research team will study Heusler alloys to identify the combinations of metal materials that could serve as platforms for future quantum technologies.

"Due to their relative ease of synthesis and tunable magnetic properties, Heusler alloys offer a conducive environment for the discovery of topologically protected magnetic phases," Kharel explained. "In addition to advancing quantum science, this project will provide undergraduate and a postdoc researcher with vital experience in cutting-edge quantum research, helping train the next generation of quantum scientists and engineers."

The three-year project, from NSF's Division of Materials Research, is funded with a $351,186 grant.
